Omar Sultan's Blog I was chatting with a customer the other day who was struggling with some of the implications of cloud computing. The analogy that finally made sense to them is what I will call 'cloud dining.'  I am the cook in the house and I am tasked with feeding the family.

Quite a few years ago, when we we positioning the concept of the intelligent network, we had a slide that showed how features moved fr... (more)

Well, clever marketing folks aside, the name was very explicitly chosen, so lets deconstruct it a bit. First of all, this is not LAN 3.0 or SAN 3.0, but Data Center 3.0. The point is that, looking ahead, you can expect a more holistic appr... (more)
